CHARLES AUGUSTUS OVERTON, OF COEUR DALENE, IDAHO.

ROOF-JOINT.

To all whom it ma concern:

Be it known thatI, CHARLES A. OVER- 'roN, a citizen of the United States, residmg at Coeur dAlene, in the county of Kootenai and State of Idaho, have invented certa1n new and useful Improvements in Roof- Joints, of which the following is a specification. i

This invention relates to devices'for forming awater-tight jointbetween a roof and a soil or other pipe passing therethrough.

The invention has for its object to pro; vide a device of the kind stated which is easy to adjust to fit pipes of different. diameters, and which grips the pipe soas to make a strong, durable and tight joint.

The object stated is attained by means of a novel combination and arrangement of parts to be hereinafter described and claimed, reference being had. to the accompanying drawing in which-- Figure 1 is a side elevation showing the application of the invention; Fig. 2 is a plan view thereof; Fig. 3 is a cross-section on the line 3-3 of Fig. 2, and Fig. 4 is front elevation.

Referring specifically to the drawing, 5

'denotes a; frusto-conical sleeve of sheet metal, having secured to its base an outstanding flange 6 wherebyit is secured to the roof in any suitable manner. The base of the sleeve is cut slanting which places.

the flange at a corresponding angle, so that the device may be applied to a sloping roof.

For fiat roofs, the sleeve. will be arranged perpendicular to the base flange. The diameter of the sleeve is suchthat the soil or other pipe 7 may pass' therethrough.

In the lower side of the sleeve 5 is a recess which is closed by a tongue 8, and from the bottom portion of this'recess extends up-.

ward a sheet metal tongue 9 which is inside the tongue 8. These two .tongues'are curved transversely to conform to the curvature ofthe sleeve-and the tongue 8 laps the tongue 9. The tongue 8 is rivetedor otherwise secured to the tongue 9, and the latter is formed integral with the sleeve 5. The width of the tongue '8 is such that it laps the inner. surfaceofthe sleeve for a short distance on opposite sides of the recess, and the side edges of said tongue, near the bot- Specificationof Letters Patent.

tom thereof, have notches 10 to receive the adjacent edges of the recessed portion of the sleeve. 1

On'opposite sides of the recess in the sleeve 5 which is covered bythe tongue 8,

at the top of the sleeve, the latter has outstanding ears 11 provided with alined perforations to receive alclamping bolt 12 secured by a nut 13. Upon drawing the ears together the sleeve 5 is contracted and that portion which. laps the tongue 8 is drawn tightly over the same and forces said tongue firmly against the tongue 9. The sleeve and 'the tongues may thus be contracted or drawn tight around the pipe? to make a water-tight joint, and the parts are also ad ustable for pipes of difi'erent diameters,

within certain limits. -The sleeve and the tongues are of course flexible so that the overlapping parts may be clamped together.

as described.

I claim: 1. A roof joint comprising a flexible sleeve having a side recess and a tongue extending upward from the bottom of therecess, a flexible tongue secured tothe sleeve to cover the'recess, said tongue lapping the inner surface of the sleeve at opposite sides of the recess and also lapping the first-mentioned tongue, and means for contracting the sleeve to clamp the aforesaid lapping parts together. Y 2. A roof joint comprising a flexible sleeve having a side recess and 'a tongue extending upward from the bottom of the recess,. a flexible tongue secured to the sleeveto cover the recess, said tongue lapping the inner surface of the sleeve at opposite sides ofthe'recess and also lapping the first-mentioned tongue, the. side edges of the flexible tongue having notches at its lower end in which the edges of the recessed portion of the sleeve seat, and means for contracting the sleeve to clamp the In testimony whereof'I afiix my signature in presence of two witnesses.
